PRODUCT INFORMATION

THE ULTIMATE COOLING SOLUTION FOR BMW F8X M3, M4, & M2 COMPETITION


The BMW F80 M3, F82/F83 M4 & F87 M2 Competiton are still regarded as some of the best performance platforms available. BMW’s S55 Motor has amazing potential for power and there are countless performance parts available for it. However, like most production engines, the S55 doesn’t come equipped from the factory with sufficient cooling capabilities to cope with added power or even prolonged performance driving. CSF have designed a full line of S55 cooling options to help you get the most out of your BMW F8X. The CSF Charge-Air-Cooler, Heat Exchanger, and Transmission Cooler will keep you ahead of the competition.


BMW F8X TOP MOUNT DUAL-PASS CHARGE-AIR-COOLER


The S55 suffers heavily from heat soak. Many tuners witnessed this early on after doing multiple dyno pulls and seeing significant drops in power after each consecutive pass. Many F8X owners experienced the same loss of power on the track as the engine just could not cool off during laps. The solution is two fold: The Charge-Air-Cooler & Front Mount Heat Exchanger work together to keep the intake temps down and power up. The factory units simply cannot dissipate enough heat to keep up with prolonged performance driving. Our Charge-Air-Cooler boasts a core size that is 60% larger, greatly increasing the capacity for heat transfer from the hot charge air coming from the turbos. Paired with the Front Mount Heat Exchanger the system is able to maintain lower intake temps and keep your BMW F8X’s power up.

The CSF Dual-Pass Top Mount Charge Air Cooler is a direct replacement for BMW part number 17517846235.

FEATURES

  • World’s 1st cast end tank designed top mount charge-air-cooler for the BMW S55 engine.

  • 60% increase in core size compared to the OEM cooler.

                                Same plastic quality as OEM but fit was off. Make sure correct clips are compatible
                                Style: 121PCS Clips with Tool for Honda/Acura, Style: 121PCS Clips with Tool for Honda/Acura
                                I ordered the version:121PCS Push Type Retainer Clips sold by ARKOUNIX. It says it is compatible for the following vehicles: Honda Accord Civic, CR-V, Crosstour, Fit, HR-V, Insight, Odyssey, Passport. It also fits the following Acura models: ILX, MDX, RDX, RLX. UNBOXING: Inside the storage box are 4 different style plush clips and 1 removal tool (pic1). This is a variety pack with 4 different style clips. The thinking being 1 of them have to fit your vehicle. The bad thing is that means 3 of these clip styles will not fit your vehicle and they will have no value for your vehicle. The push clips that I need for my car are the longer style #4 clips (pic3). FIT: The Arkounix brans replacements are on the left (next to the tool) and my car's OEM clips are on the right so you can see how they measure up (pics3-5). These Arkounix clips are close but not an exact match. They are about 2 mm too wide to fit in my bumpers slot. For reference, my car is a Mazda 6. I understand it's not meant to be compatible but they are very similar in picture and I thought it would fit. CONCLUSION: These clips are not sized for a universal fit. This kit has 4 distinct clip sizes that are specifically designed to fit ONLY the car models listed above. If you're hoping that these clips will fit a different make and model, make sure to check the measurements of your OEM clips first. I found out the hard way that just because the clips look similar doesn't make them compatible. A width different of just 2mm was enough to make these replacement clips incompatible with my car. I can say with certainty that these 4 sizes of Arkounix brand clips will NOT fit a Mazda 6, Pontiac G5 or Toyota Corolla because, I tried fitting these clips on both of my neighbor's cars. In conclusion, these clips are made to fit the specific Honda and Acura models listed above, ONLY.

                                Just get them if you think u need them!
                                Style: 121PCS Clips with Tool for Honda/Acura
                                They got just as well as the original ones in my opinion. As long as the place you're putting them in isn't damaged they fit very snug like they're supposed to. Even came with a tool to pry them off with. I already had one before I ordered these but I did appreciate that they came with the tool just in case you don't have one. The tools make the job a lot easier. I feel like I got a good deal. For just a few dollars my car looked a little better and made a little less noise since the piece I put the fastener on would rattle a bit depending on the road but not anymore! If u need these and are wondering wether you should buy them just go for it. You really don't have much to lose and they always come in handy and are good to have around. They also fit on some other cars like Nissan and probably many more too. So far they seem pretty durable but only time will tell and I will update my review if anything should happen but for now, I feel like it was money well spent. Unlike some of my other purchases!

                                Spot on! Used it to secure my new grill and bumper for my 97 civic. Nice quality fasteners. Super cheap price. Simple enough to use and the different sizes were clutch for what I needed.

                                These are quality bulbs and more reliable than halogen

                                Car that I drive is a 2008 Mazda 3 4Dr Sedan Automatic i Touring. Got so tired and fed up with felt like spending money every month or so on halogen bulbs. It was always the same old story, trip to auto zone to avoid a fix it ticket. I almost tried to buy the Sylvania brand on Amazon for cheaper but what's the use? Its STILL the SAME product. I'm done with those and never going back. The new Territory Has snapped right in without any special add on adapters, just plug and play deal. Way brighter and super easy. Love them. Can see way better at night and not have to worry about them burning out so quickly anymore. More than I can say about the Sylvania brand "Made in Germany". They're slippin
